CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of and priority to U.S. Provisional patent application Ser. No. 16/160,815 filed on Oct. 15, 2018, which application is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

Flasks are a known device for carrying a beverage, and are often used for carrying alcoholic spirits. They may be insulated or be as simple as a sealable container that allows a user to carry the beverage as desired. They typically have opaque walls to hide the type of liquid being carried. However, flasks share a number of drawbacks.

In particular, flasks generally do not include a tumbler. Instead a user drinks straight from the flask. Thus, if a user wants to drink from the flask, he/she does so directly from the bottle. In there is a desire to share the beverage stored in the flask, then it is generally done in a non-sanitary way. Those flasks which do include a tumbler include only a single tumbler resulting in the same issues of sharing a drinking implement.

Moreover, these tumblers are attached in ways that are not easily accessed. For example, they may be threaded or otherwise attached. In addition, they are often attached directly over the cap of the flask, meaning that for even a small drink the user must unscrew the tumbler, remove the cap, pour the beverage from the bottle into the cup, reattach the cap, the screw the tumbler back onto the flask. In addition, the threading is in the location where the user places his/her lips which can lead to injury such as cuts on the user's lips.

Accordingly, there is a need in the art for a flask with more than one tumbler. In addition, there is a need in the art for an attachment method for the tumbler which is easier for a user than threading.

DETAILED DESCRIPTION OF SOME EXAMPLE EMBODIMENTS

Reference will now be made to the figures wherein like structures will be provided with like reference designations. It is understood that the figures are diagrammatic and schematic representations of some embodiments of the invention, and are not limiting of the present invention, nor are they necessarily drawn to scale.

FIGS. 1A-1O (collectively “FIG. 1 ”) illustrate an example of a transportable flask with attached tumblers 100. FIG. 1A illustrates a side view of the example of a transportable flask with attached tumblers 100; FIG. 1B illustrates a top view of the example of a transportable flask with attached tumblers 100, with the bottom view being a mirror image thereof; FIG. 1C illustrates an isometric view of the example of a transportable flask with attached tumblers 100; FIG. 1D illustrates an expanded side view of the example of a transportable flask with attached tumblers 100; FIG. 1E illustrates an expanded top isometric view of the example of a transportable flask with attached tumblers 100; FIG. 1F illustrates an expanded bottom isometric view of the example of a transportable flask with attached tumblers 100; FIG. 1G illustrates a top view of the example of a tumbler from a transportable flask with attached tumblers 100; FIG. 1H illustrates a bottom view of the example of a tumbler from a transportable flask with attached tumblers 100; FIG. 1I illustrates a top isometric view of the example of a tumbler from a transportable flask with attached tumblers 100; FIG. 1J illustrates a top view of the example of a bottle from a transportable flask with attached tumblers 100; FIG. 1K illustrates a bottom view of the example of a bottle from a transportable flask with attached tumblers 100; FIG. 1L illustrates a top isometric view of the example of a bottle from a transportable flask with attached tumblers 100; FIG. 1M illustrates a top view of the example of a cap from a transportable flask with attached tumblers 100; FIG. 1N illustrates a bottom view of the example of a cap from a transportable flask with attached tumblers 100; and FIG. 1O illustrates a top isometric view of the example of a cap from a transportable flask with attached tumblers 100. The transportable flask with attached tumblers 100 includes everything that a user needs to transport and share a liquid beverage, whether cooled or heated. That is, the transportable flask with attached tumblers 100 can be used to transport a liquid beverage, even if the liquid beverage is not ambient temperature, and share the liquid beverage amongst two people without forcing them to share a cup.

FIG. 1 shows that the transportable flask with attached tumblers 100 can include a bottle 102. The bottle 102 is both thermally insulated and configured to hold a liquid beverage (e.g., the bottle 102 is waterproof). Thermal insulation is the reduction of heat transfer (i.e. the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. Heat flow is an inevitable consequence of contact between objects of different temperature. Thermal insulation provides a region of insulation in which thermal conduction is reduced or thermal radiation is reflected rather than absorbed by the lower-temperature body. As used in the specification and the claims, the phrase “configured to” denotes an actual state of configuration that fundamentally ties recited elements to the physical characteristics of the recited structure. That is, the phrase “configured to” denotes that the element is structurally capable of performing the cited element but need not necessarily be doing so at any given time. Thus, the phrase “configured to” reaches well beyond merely describing functional language or intended use since the phrase actively recites an actual state of configuration.

FIG. 1 also shows that the transportable flask with attached tumblers 100 can include a cap 104. The cap 104 is configured to attach to the bottle 102. The cap 104 is a protective lid or cover which seals the interior of the bottle 102. I.e., the cap 104 allows a user to access the liquid beverage in the bottle 102. The cap 104 needs to completely seal the bottle 102 such that the liquid beverage remains within the bottle 102 when the cap 104 is in place.

FIG. 1 further shows that the transportable flask with attached tumblers 100 can include threading 106. For example, the cap 104 can include male threading 106 which mates with female threading 106 in the neck of the bottle 102. A threading 106, sometimes called a screw thread, is a helical structure used to convert between rotational and linear movement or force. I.e., a thread 106 is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread. Thus, the thread 106 converts rotation of the cap 104 to linear motion of the cap 104 to linear motion of the cap 104 relative to the bottle 102.

The mechanical advantage of a thread 106 depends on its lead, which is the linear distance the screw travels in one revolution. In most applications, the lead of a thread 106 is chosen so that friction is sufficient to prevent linear motion being converted to rotary, that is so the cap 104 does not slip even when linear force is applied, as long as no external rotational force is present. Thread lead and thread pitch are closely related concepts. The difference between them can cause confusion, because they are equivalent for some screws. Lead is the distance along the screw's axis that is covered by one complete rotation of the screw (360°). Pitch is the distance from the crest of one thread to the next. Because the vast majority of screw threadforms are single-start threadforms, their lead and pitch are the same. Single-start means that there is only one “ridge” wrapped around the cylinder of the screw's body. Each time that the screw's body rotates one turn (360°), it has advanced axially by the width of one ridge. “Double-start” means that there are two “ridges” wrapped around the cylinder of the screw's body. Each time that the screw's body rotates one turn (360°), it has advanced axially by the width of two ridges. Another way to say the same idea is that lead and pitch are parametrically related, and the parameter that relates them, the number of starts, often has a value of 1, in which case their relationship becomes equivalence. Single start threads will be assumed herein unless otherwise specified.

Specifying the lead of a thread form can include metric based or inch-based standards. For example, inch-based standards usually use threads per inch (TPI), which is how many threads occur per inch of axial screw length. Lead and TPI describe the same underlying physical property—merely in different terms. When units of measurement are constant TPI is the reciprocal of lead and vice versa. For example, a ¼-20 thread has 20 TPI, which means that its lead is 1/20 inch (0.050″). Metric based standards can measure the threads per millimeter or threads per centimeter.

FIG. 1 additionally shows that the transportable flask with attached tumblers 100 can include a seal 108. The seal 108 prevents leaks between the cap 104 and the bottle 102. For example, the seal 108 can include a silicone gasket that is placed around a portion of the cap 104. I.e., the seal 108 stays in place around the cap 104 such that when a user places the cap 104 on the bottle 102 the seal prevents any leakage between the bottle 102 and the cap 104. In particular, rotation of the cap 104 relative to the bottle 102 can exert force on the seal 108 via the threads 106 which compresses the seal 108.

FIG. 1 moreover shows that the transportable flask with attached tumblers 100 can include a pair of cups 110. The pair of cups 110 are identical to one another and are secured to portions of the bottle 102 and/or the cap 104, as described below. The cups 110 are small, bowl-shaped containers for drinking. I.e., the cups 110 receive the liquid beverage from the bottle 102, allowing a user to drink the liquid beverage.

FIGS. 2A-2D (collectively “FIG. 2 ”) illustrate a cutaway view of the example of a transportable flask with attached tumblers 100. FIG. 2A illustrates a side cutaway view of the top of the transportable flask with attached tumblers 100; FIG. 2B illustrates a side cutaway view of the top of the transportable flask with attached tumblers 100 including surface shading; FIG. 2C illustrates a side cutaway view of the bottom of the transportable flask with attached tumblers 100; and FIG. 2D illustrates a side cutaway view of the bottom of the transportable flask with attached tumblers 100 including surface shading. The transportable flask is meant to be capable of serving a liquid with all pieces attached. I.e., the transportable flask with attached tumblers 100 holds a liquid for transportation, such as hiking, and then allows the beverage to be enjoyed and shared upon reaching the user's destination.

FIG. 2 shows that the bottle 102 (and/or the pair of cups 110) can include a double wall 202. The double wall 202 acts to insulate the bottle 102. That is, the double wall 202 includes a low thermal conductivity material which slows heat transfer between the bottle 102 and the outside environment. For example, the double wall 202 can include a vacuum or other desired material. The benefit of a vacuum is that a puncture in one or both of the walls in the double wall 202 does not result in a substance leaking into the liquid beverage. I.e., there are no possible ill health effects of a puncture of one of the walls in the double wall 202.

FIG. 2 also shows that the bottle 102 (and/or the pair cups 110) can include an inner coating 204. The inner coating 204 prevents any change in the liquid beverage flavor. For example, the inner coating 204 can include electropolished stainless steel. Electropolishing, also known as electrochemical polishing, anodic polishing or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece. It is used to polish, passivate, and deburr metal parts. It is often described as the reverse of electroplating. It may be used in lieu of abrasive fine polishing in microstructural preparation. Typically, the work-piece is immersed in a temperature-controlled bath of electrolyte and serves as the anode; it is connected to the positive terminal of a DC power supply, the negative terminal being attached to the cathode. An electrical current passes from the anode, where metal on the surface is oxidized and dissolved in the electrolyte, to the cathode. At the cathode, a reduction reaction occurs, which normally produces hydrogen. Electrolytes used for electropolishing are most often concentrated acid solutions having a high viscosity, such as mixtures of sulphuric acid and phosphoric acid. Other electropolishing electrolytes reported in the literature include mixtures of perchlorates with acetic anhydride and methanolic solutions of sulphuric acid. One of the benefits of electropolishing for stainless steel is that it removes iron from the surface and enhances the chromium/nickel content for the most superior form of passivation for stainless steel. Electropolishing also provides a clean and smooth surface that is easier to sterilize, while improving the surface finish by levelling micro-peaks and valleys.

FIG. 2 further shows that the cap can include a first magnet 206 in the cap 104. A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. As used herein, magnets are paired with one another. The pair of magnets can include either two permanent magnets or a permanent magnet and a ferromagnetic material.

Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of magnetism.

Ferromagnetic materials can be divided into magnetically “soft” materials like annealed iron, which can be magnetized but do not tend to stay magnetized, and magnetically “hard” materials, which do. Permanent magnets are made from “hard” ferromagnetic materials such as alnico and ferrite that are subjected to special processing in a strong magnetic field during manufacture to align their internal microcrystalline structure, making them very hard to demagnetize. To demagnetize a saturated magnet, a certain magnetic field must be applied, and this threshold depends on coercivity of the respective material. “Hard” materials have high coercivity, whereas “soft” materials have low coercivity. The overall strength of a magnet is measured by its magnetic moment or, alternatively, the total magnetic flux it produces. The local strength of magnetism in a material is measured by its magnetization.

FIG. 2 additionally shows that the transportable flask with attached tumblers 100 can include a second magnet 208 in the bottom of the bottle 102. I.e., the bottom of the bottle 102 has a magnet (or ferromagnetic material) within the double wall 202 of the bottle 102. Whatever is used in the cap 104 will generally be used in the double wall 202 of the bottle 102 and vice versa. That is, if the first magnet 206 is a permanent magnet then the second magnet will likewise be a permanent magnet and if the first magnet 206 is ferromagnetic material then the second magnet 208 will be ferromagnetic material. In addition, the polarity of the first magnet 206 will be opposite the second magnet 208. E.g., if the polarity of the first magnet 206 is such that the positive pole is directed upward when the cap 104 is secured to the bottle 102 then the polarity of the second magnet 208 will be such that the positive pole is directed downward. I.e., the orientation of the first magnet 206 and the second magnet 208 are both such that the positive pole is the same relative to the center of the bottle 102 (e.g., both positive poles point toward or away from the center of the bottle 102).

FIG. 2 moreover shows that the transportable flask with attached tumblers 100 can include a third magnet 210 a and a fourth magnet 210 b (collectively “cup magnets 210”). The cup magnets 210 secure the pair of cups 110 to the bottle 102 and the cap 104 for transporting. In particular, the polarity of the cup magnets 210 are aligned to be opposite the polarity of the first magnet 206 and second magnet 208 (e.g., if the positive pole of the first magnet 206 and the second magnet 208 both point away from the center of the bottle 102 then the negative pole of the cup magnets points to the center of the bottle 102 when the cups are in place). Therefore, when one of the cups 110 is placed near the bottom of the bottle 102 (i.e., in proximity to the first magnet 206) there is a magnetic attraction which holds the cup 110 in place. Likewise, when one of the cups 110 is placed near cap 104 (i.e., in proximity to the second magnet 208) there is a magnetic attraction which holds the cup 110 in place.
